What changed for QSBS in 2025?
The One Big Beautiful Bill Act, enacted in July 2025, expanded QSBS for stock issued after July 4, 2025: partial exclusions at three and four years, a higher $15M per-company cap, and a $75M gross asset limit. The Section 1045 rollover rules didn’t change.
For stock issued after July 4, 2025
- Exclusion of 50% at three years, 75% at four years, and 100% at five years.
- Per-company cap of the greater of $15M (indexed for inflation) or 10 times basis.
- Gross asset limit of $75M (indexed).
For older stock
The prior rules still apply: 100% exclusion at five years, nothing before, a $10M or 10 times basis cap, and a $50M gross asset limit.
Rollovers
You still need more than six months of holding and 60 days to reinvest. How the new tiers apply to replacement stock bought in a rollover is a question for your advisor.
